Benjamin-Plus is an instruction-set skill for coding agents that aims to reduce token and tool-call usage without changing the agent's implementation task. It teaches five operating habits: batch repository reconnaissance into one pass, inspect narrow file windows unless full data is needed, probe dependencies in one command, treat the task's specified verification command as the definition of done, and poll unfinished builds at longer intervals rather than repeatedly checking them.
The skill is intended to be injected into an agent's instructions rather than installed as a discoverable skill. Its repository provides an injected instruction file for Claude Code hooks, Codex CLI's AGENTS.md, project CLAUDE.md files, or other agents' system prompts. The project reports measured cost reductions ranging from about 10% to 18% depending on baseline behavior, with unchanged quality in its reported evaluation; it also documents a cross-platform Java SWE-bench measurement with reduced cost and tool calls.

An instruction set for coding agents intended to reduce token usage without changing results. It batches repository reconnaissance, reads narrow file windows, probes dependencies once, and follows the task's verification command.
